SLEEPING BAG As is known, it is desirable to have a sleeping bag whichis compact in a transporting position and which is readily erected foruse. Previous approaches to sleeping bags were heavy and/or cumbersome,failing to provide self-contained features for safety, comfort and easein erection.

The invention satisfies all of the aforesaid requirements. Briefly, thepresent sleeping bag is readily rolled for transporting, being light inweight and easy to handle, and, subsequently, is readily erected foruse. The sleeping bag includes a stowage compartment for mosquitonetting and a protective covering, each being-selfcontained and securedat a portion thereof to the sleeping bag. Collapsible framework membersare provided over which the aforesaid mosquito netting and protectivecovering are disposed. Slide fastener means on the mosquito netting andon the protective covering effectively mesh with corresponding structuredisposed on the sleeping bag. A cushioning layer is provided over aninflatable air mattress, the latter being readily replaced in the eventof wear or damage. Assembly of the sleeping bag of the invention iseasily accomplished through simple action.

A better understanding of the invention will become more apparent fromthe following description, taken in conjunction with the accompanyingdrawings, wherein FIG. 1 is a perspective view, partly fragmentary andpartly in section, showing the sleeping bag of the invention;

FIG. 2 is a view in vertical section, also partly fragmentary, showingcertain details of the invention;

FIG. 3 is a fragmentary perspective view of a portion of the collapsibleframework feature;

FIG. 4 is 'a view in side elevation, partly fragmentary and partly invertical section, showing details of the stowage compartment of thepresent sleeping bag, where certain overall fastening details areomitted for drawing clarity; and,

FIG. 5 is a fragmentary view in side elevation showing the access end ofthe sleeping bag after assembly for use.

For the purposes of promoting an understanding of the principles of theinvention, reference will now be made to the embodiment illustrated inthe drawings and specific language will be used to describe the same. Itwill nevertheless be understood that no limitation of the scope of theinvention is thereby intended, such alterations and furthermodifications in the illustrated device, and such further applicationsof the principles of the invention as illustrated therein beingcontemplated as would normally occur to one skilled in the art to whichthe invention relates,

Referring now-to the figures, the sleeping bag of the inventioncomprises a layer 12 of cushioning material, the latter typically beingkapok or the like, encased within a waterproof covering 14. Covering 14has another waterproof lower covering 16 secured thereto, as bystitching, along the lower portion of one side wall thereof. Asparticularly evident from FIGS. 1 and 2, the lower covering 16 isadapted to receive an inflatable air mattress 17, where the free end ofthe lower covering 16 is secured to the opposite side wall of covering14 through the means of snap fasteners 19 (see FIGS. 4 and 5).

When the air mattress 17 is initially positioned within the lowercovering 16, the lower covering 16 assumes a loose condition. When theair mattress 17 is inflated, however, the lower covering 16 assumes thecondition of FIG. 2. The snap fasteners 19 provide for the ready removalof the air mattress 17 in the event of damage, as by puncturing, or thelike. Conventional means (not shown) are provided for inflating the airmattress 17.

One end of the covering 14, as well as the lower covering 16, isextended to provide a stowage compartment 20, where the access to suchstowage compartment 20 is typically provided through slide fastener 22.The stowage compartment 20 receives an outer covering 24, as well asmosquito netting 25, where one end of each is secured, as by stitching,to a portion inside of the stowage compartment 20. In other words, theouter covering 24 and the mosquito netting 25 may be folded and/orstored within the stowage compartment 20 to provide a self-containedarrangement (see FIG. 4).

A slide fastener assembly 24a and a slide fastener assembly 25a extendaround the sleeping bag, beginning at a corner thereof proximate to theaforesaid stowage compartment 20. As should be evident from FIG. 2, theslide fastener assemblies 24a and 25a are secured to the vertical wallsdefining the sides and the access end of the covering 14. In thisconnection, it should be understood that the side edges and the frontend edges of the outer covering 24 and the mosquito netting 25 containslide fastener teeth, so that slide fastening can be readily achievedwith slide fastener assemblies 24a and In order to accomplish theerection of the sleeping bag for use, a series of pockets 27 areprovided along the side walls of the covering 14. The aforesaid pockets27 receive the ends of telescopic framework members 29, the latter beingdefined by sections 29a and 29b. The framework members 29 are made froma resilient material and are arced to assume the positioning evi' dentin FIG. 1 and in the detail of FIG. 3. The framework members 29 arereadily flexed for use and are easily carried, in a rolled condition,when the sleeping bag is being transported.

With reference to FIG. 5, the end of the sleeping bag opposite thestowage compartment 20 is the access opening, where a slide fastener 30is provided for ready entry. While not shown,-the outer covering 24 andthe mosquito netting 25 also include slide fastening means proximate theslide fastener 30 to permit access. The sleeping bag further includesring-like members 32 for purposes of staking. Additionally, and whilenot shown, the outer covering 24 may include flap portions to provideventilation.

As should be evident from the preceding, the sleeping bag of theinvention is readily assembled for use. In this connection, the sleepingbag is unrolled from a normally rolled transporting condition and theair mattress l7 inflated. Thereafter, the framework members 29 areflexed and the ends thereof positioned within pockets 27. The outercovering 24 and the mosquito netting 25 are removed from the stowagecompartment 20 and placed over the framework members 29, wherepositioning is retained through the use of slide fastener assemblies 24aand 25a. As stated, entry into the sleeping bag is accomplished throughslide fastener 30.

The sleeping bag is susceptible to various changes within the spirit ofthe invention. For example, proportioning can be changed and otherapproaches utilized for the selective positioning of the frameworkmembers. Aside from ease in erection, another important feature of theinvention is its capability of ready rolling for transporting, beingcompact, light in weight, and easy to handle. Thus, the precedingdescription should be considered illustrative, and not as limiting thescope of the following claims:

I claim:
